Working principle
Air enters through the air inlet and is directly driven by a magnetic-levitation high-speed permanent-magnet motor to a three-dimensional impeller. Under the high-speed rotation of the impeller, kinetic energy and pressure potential energy are generated. Part of the kinetic energy is converted into pressure potential energy in the diffuser and volute passages, where the flow direction is altered. Finally, the air is discharged through the exhaust pipe into the pipeline network, achieving an aeration effect.
Rongheng Power, with magnetic levitation motors and bearing controllers at its core, leverages advanced DA regulation technology to achieve energy savings and high efficiency in blower operation.
Core Technologies and Components
High-efficiency and stable inverter
The motor operates using a state-of-the-art high-frequency inverter to adjust the frequency of the high-speed permanent-magnet motor. It features a built-in filter to suppress internal electromagnetic interference and independent cooling. The system can adapt its parameters automatically to different operating conditions, enabling automated control and unattended operation.
With independent R&D and design capabilities, and mastery of platform-level technology in the magnetic levitation industry, we are able to meet the demands of a wider range of magnetic levitation products.

Energy-saving benefits
| An industrial wastewater treatment and renovation project |  Note: In wastewater treatment plants that use blower aeration processes, the power consumption of the blowers... Accounting for approximately 45-60% of the plant’s total power consumption, after adopting Rongheng Power’s magnetic levitation blowers, It can save them 30-50% in costs. | ||
| Type | Original Roots blower | Magnetic levitation blower | |
| Quantity | 2 units | 1 unit (1 unit replaces 2 units) | |
| Run Parameter | 2 × 80 kW 58.8 kPa 80 m³/min | 100kW 58.8 kPa 80 m³/min | |
| Energy saving Analysis | Rongheng magnetic levitation blowers replace two units with just one. The original Roots blower achieves energy savings of 37.5%. | ||
Core advantages
Small size, easy to install The entire unit features an integrated design with a skid-mounted structure. It incorporates internal components such as fluid devices, motors, and variable-frequency drives, resulting in a compact and lightweight configuration. It requires no complicated equipment foundations or large lifting equipment, making installation simple and allowing for one-button start-up and shutdown. | Smart control, real-time monitoring By adopting IoT modules, we can monitor the operational status of wind turbines in real time. Utilizing LCP, MCP, and DCS control systems, we can adjust control parameters in real time, providing customers with more convenient and personalized services. |
Energy-saving and efficient It employs a high-efficiency centrifugal impeller designed in-house, paired with a high-speed permanent-magnet synchronous motor. Compared to conventional positive-displacement equipment, it achieves energy savings of approximately 30%; compared to multi-stage centrifugal equipment, it saves about 20%; and compared to conventional single-stage centrifugal equipment with gear speed increase, it saves roughly 15%. | Low vibration, low noise Thanks to magnetic levitation technology, the rotating and stationary components inside the fan have no mechanical contact and no friction, resulting in a sound pressure level below 80 dB(A), quiet operation, and low vibration. |
Oil-free, friction-free Thanks to the adoption of advanced magnetic levitation bearing technology, which eliminates the need for the gearboxes and oil-lubricated bearings typically required in conventional equipment, the entire machine is completely oil-free. | Easy maintenance, multi-level protection Utilizing magnetic levitation bearing technology, the system features no gearbox or lubrication system components, eliminating the need for mechanical maintenance. Daily upkeep involves only replacing the air filter. It offers triple power-off protection plus timely and reliable after-sales support. |
